WIRE CHAIN-LINK.

SPECIFICATION forming part of Letters Patent No. 447,597, dated March 3, 1891.

Application filed November 3, 1890- Serial No. 370,142. (No model.)

To all whont it may concern:

Be it known that I, ORRIN D. \VRIGHT, of Kenwood, in the county of Madison, in the State of New York, have invented new and useful Improvements in \Vire Chain-Links, of which the following,'taken in connection with the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to provide a chain-link formed of wire in a simple and inexpensive manner and which shall have its longitudinal members straight and parallel, and thus possess maximum strength, and shall require only the twisting of one of the extremities of the wire in the operation of completing said link after it has been connected to the chain; and to that end my improved chain-link is formed of a single piece of wire having its central or main portion straight and its end portions bent back toward each other and parallel with the main portion, one of said end portions being terminated with a head standing at right angles toward the main portion and the other end portion terminating in an eye standing in a plane at right angles to said end portion and embracing the first-named straight end portion immediately back of the head, as hereinafter more fully described, and specifically 0 set forth in the claim.

In the annexed drawings, Figure 1 is a side view of a portion of a chain composed of links embodying my invention, and Fig. 2 is a plan view of a blank from which my improved link is formed.

a represents the chain-link, which I form of a blank consisting of a single piece of wire having its central or main portion Z maintained straight and its end portions Z Z bent back toward each other and parallel to the main portion Z and overlapping each other at their extremities, as shown in Fig. 2 of the drawings. The end portion Z is terminated with the head 7L or short right-angled bend pref- 5 erably toward the main portion Z to obviate projections on the exterior of the link.

In completing the link the -extremity of the end portion Z of the wire is coiled in the form of an eye 8, standing in a plane at right angles to the length of the link and embrac- 5o ing the straight end portion Z", immediately back of the head h, as shown in Fig. 1 of the drawings, said head alfording a secure hold for the eye 6 to prevent it from slipping endwise off from the end portion Z" of the wire.

The described blank is readily formed by bending the wire over a suitable form having two straight parallel sides meeting with curved ends, the central portion of the wire being held against one of the straight sides of the form, while the end portions ofthe wire are bent around the curved ends of the form and against the opposite straight side thereof. The short bend or head h may be made before bending the wire around the form, as aforesaid. This blank is readily connected to a chain-link by slipping one side or one end of the latter through between the flexible ends of the blank and then tying the ends of the blank to complete the link by bending the straight overlapping end of the wire around the opposite end thereof immediately back of the head h. Hence a chain composed of links formed as aforesaid can be readily repaired or lengthenedwhen desired by adding other links of the aforesaid form thereto.

Having described my invention,what I claim as new, and desire to secure by Letters Patent, iS

The improved chain-link composed of a single piece of wire having its central or main portion straight and its end portions bent back toward each other and parallel with the main portion, one of said end portions being terminated with the head h, standing at right angles toward the main portions, and the other end portion terminating in an eye 6, standing in a plane at right angles to said end portion and embracing the first g( named end portion immediately back of the head it, substantially as described and shown.

In testimonywhereof I have hereunto signed my name this 29th day of October, 1890.
